Tough to beat this Vitamin B mix (B-1, B-2, B-6, B-12) all in one pill. Vitamin B has huge benefits and we often don't get enough in our daily diets given how bad processed food has gotten these days. GNC product so it's been highly tested and run through a million quality checks. Good addition to vitamin cabinet.

I generally take at least one every day. Been doing that for years and feel just fine. I always take with 2K of Vitamin C to help with absorption. Especially helpful if you drank a few too many the night before. Replaces the vitamins you lost.

The Big 100 B-Complex is a great combination of multiple types of Vitamin B. I would suffer from mouth ulcer under stress and not sufficient B intake usually for more a week, but it relieves my slight initial symptom right after one day's intake. It really works!

My doctor recommeded me to take Vitamin B regularly, and he recommended GNC! I am always confident of GNC quality. It is an easy job to just take one tablet daily, you will never forget it. Good! keep me healthy! by the way, I think I will also buy some for my Mum for the Mother's Day.

I purchase all my vitamins and minerals through GNC. The Big 100 B-Complex added the extra kick I needed in my step. My girlfriend has followed suit and she also takes a vitamin regimen purchased at GNC. This product gets an A++ from us. Thank you GNC for providing us with the expert advice we needed.

My B12 vitamin level is too low. My doctor told me to start taking an over the counter B12 vitamin with at least 1000 mcg. The label on GNC B-Complex Big 100 isn't clear whether or not it has B12 1000 mcg per tablet. It exceed the daily requirement. Does it have at least 1000 mcg per tablet? If so, how many mcg per tablet? Thank you, Pat

BEST ANSWER:I know this is dated, but I couldn’t let such obviously incorrect information sit here without addressing. Someone read the label VERY incorrectly. This product contains 100 MILLIGRAMS of B-12. Not MICROGRAMS. Since 1000 mcg = 100 mg, this product is exactly perfect for the OP’s requirements.
